It takes hardly 2 mins 20 seconds to boil about 0.7 litre water. excellent boiling capacity. More you boil, more time wiil take, The fact is the timing and performance is pretty good. The outer body gets hot as the water starts boiling. And it will remain hot for quite sometime, keep away from children. Excellent looks, The handle of this kettle is good as you will not feel the heat of the Stainless Steel body. I am making my life easier........... Are You ?
